Abstract
A railroad rail support system is provided which utilizes tire carcasses filled with annular concrete cores. Railroad rails are attached to the concrete tire carcasses by means of load distribution plates anchored to the concrete cores and hold-down clips which are attached to the load distribution plates and retain the rail flanges against lateral and excessive vertical displacement with respect to the load distribution plates. Gage bars may extend between opposed pairs of ties and be anchored in the concrete cores to retain proper gage spacing of the rails.

12. A railroad construction comprising:
-
first and second elongated metal rails in spaced parallel relationship, each said rail having a rail flange; a plurality of tire ties supporting each said rail, each said tire tie comprising, an annular tire body having a tread portion and upper and lower sidewall portions surrounding a central opening, an annular concrete core filling at least a portion of said annular tire body and having a central opening aligned with said central opening in said tire body, a pair of load distributing tie plates disposed on said upper sidewall portions of said tire bodies on opposite sides of said central opening for supporting said rails on said tire ties and for distributing the load imposed by said rail across a portion of each said tire tie, anchor means for anchoring each said tie plate to said annular concrete core, and hold-down clips attached to said tie plates and extending above said rail flange so as to retain said rail in position on said tie plates; and ballast disposed in surrounding relationship to at least part of said tread portions of said tire ties and filling at least a portion of said central openings defined by said tire bodies and said annular concrete cores. - View Dependent Claims (13, 14, 15)
